The FAFCO Solar Bear Solar Pool Heater is designed for both above-ground and in-ground swimming pools, though it is not recommended for inflatable pools. This system utilizes solar energy to heat pool water, offering an environmentally friendly and cost-saving alternative to traditional energy sources.
Function Description:
The Solar Bear system operates by circulating pool water through a solar collector heated by sunlight. The warmed water then returns to the pool, increasing its temperature. The system includes one solar collector, mounting hardware, connection hardware, and an integrated bypass valve. For optimal performance, the solar collectors should be installed in an unshaded location that receives full sun for most of the day, ideally tilted 10 to 30 degrees towards the South. They can also be effective when facing West, East, or mounted flat. The solar collector inlet (from the pump and filter) must always be at the lowest point of the solar collectors, unless mounted flat.
Important Technical Specifications:
The standard system includes a 4' x 20' wide solar collector with 1-1/2" barb connections. The package contains 12 mounting caps, 12 mounting bases, 6 mounting straps, 1 valve handle, and 20 rubber tube plugs.
For flexible pool hose installations, 1-1/2" I.D. flexible hose is required. Ground spikes are needed for ground installations. For roof or rack mounting, 1/4" x 2" long outdoor screws and roof sealant are necessary, along with ground rack lumber and materials if building a rack. Tools required include a flat head screwdriver or 5/16" nut driver, and for roof/rack mounting, a power drill with a 1/8" pilot drill bit and a Phillips head bit.
For rigid PVC pipe installations, additional materials include PVC primer, PVC cement, PVC fittings (two 1-1/2" PVC tees, six 1-1/2" PVC elbows), and 1-1/2" Sch.40 PVC pipe. Tools for rigid PVC include PVC pipe cutters or equivalent, a flat head screwdriver or 5/16" nut driver, and a power drill with a 1/8" pilot drill bit and a Phillips head bit. The solar collector ends have 1-1/2" barbed hose connections, or these can be unthreaded to use 1-1/2" MPT threads for rigid PVC pipe connections.
Usage Features:
The installation process involves determining an unshaded location, rolling out the solar collector, strapping it down, and connecting it to the pool. For ground installations, the collectors can be laid on grass, gravel, or landscaping bark, or a wooden rack can be built. Roof installations require a composition asphalt or equivalent roof surface. The system is not suitable for uneven surfaces like tile or metal roofs.
During startup, the red handle on the bypass valve should be parallel with the end-pipe (solar off position). After turning on the pool pump and checking for leaks, the red handle is slowly turned to the 'Solar On' position. Optimal flow is achieved when the filter pressure gauge increases by 5-7 psi. Air purging from the collector during startup is normal and will bubble out into the pool for a few minutes.
For best results, the Solar Bear should be operated when the solar collectors are in the sun. Turning the pump and solar off at night, when cloudy, or raining can prevent cooling the pool. A pool blanket is recommended to retain heat and accelerate heating. If the pool becomes too warm, running the pump and solar at night can help cool it.
Maintenance Features:
Annual winterization is crucial to prevent freeze damage, which is not covered under warranty. The solar collector must be completely drained and isolated before winter. This involves turning off the pool pump, plugging the pool inlet and outlet, disconnecting the solar collector, and manually lifting and tilting it back and forth until all water is drained. The drained solar collector should then be stored in a conditioned space (above 40°F). Open pipe or hose connections should be capped. Operating the solar system during freezing conditions is not an approved freeze-protection method, and methods like blowing lines with a shop vacuum or compressor are not guaranteed to remove all water.
The manual also provides a troubleshooting guide for common issues such as the system not heating, insufficient warmth, bubbles in the pool, reduced flow/excessive filter pressure, and the pool being too hot.
A tube leak in the solar collector can be repaired if the damage is at least 3" away from the header. The repair involves using supplied repair plugs, soapy water, a utility knife, and a small screwdriver or hex wrench. The procedure requires cutting out a 1 to 1-1/2" section of the damaged tube and inserting two plugs to isolate it.
The product comes with a limited ten-year warranty covering defects in materials and workmanship under normal use and service. The warranty requires proper installation according to instructions and routine maintenance. It does not cover conditions resulting from defects in non-SolarBear components, significant deviations from installation instructions, internal freezing due to improper maintenance, misuse, abuse, neglect, accidents, alterations, normal fading or minor exterior deterioration, or damage caused by natural phenomena. The warranty does not guarantee specific pool temperatures.
